The twisty columns of the double helix are phosphate and sugar(deoxyribose), which are bonded by a covalent bond. Each nucleotide consists of one of each, and also a nitrogen base. The rungs are nitrogen bases, each nucleotide has one base, and one side of the ladder bonds to the other side of the ladder through hydrogen bonding of complementary base pairs. The base pairs of DNA are A-T and C-G
Your question is lacking the necessary answer options, so I will be adding them here:
A. standard deviation.
B. mean.
C. median.
D. correlation coefficient.
E. range.
So, given your question, the statistical measure which is most helpful for indicating the extent to which high school grades predict college grades is: D. correlation coefficient.
A statistical measure can be defined as a numerical measurement of each value of a quantitative variable in a given population. Some of the commonly used statistical measure in science include the following;
Correlation coefficient can be defined as a statistical measure used for the measurement of the strength of the relationship between two (2) known variables and to represent their linear interdependence. Thus, the values of a correlation coefficient typically range from +1 (strong positive relationship) to -1 (strong negative relationship)
Hence, correlation coefficient is a statistical measure which is most helpful for indicating the extent to which high school grades predict college grades because it would determine the strength of the relationship between them.

<h2>Down Syndrome</h2>
Explanation:
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
- Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
- With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
- Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus
